Multifractal detrended moving average analysis of Kepler stars with surface differential rotation traces
D. B. de Freitas, M. M. F. Nepomuceno, J. G. Cordeiro +2
A multifractal formalism is employed to analyse high-precision time-series data of \textit{Kepler} stars with surface differential rotation traces. The multifractal detrended movin…
Debris disks among Kepler solar rotational analog stars
R. Silva Sobrinho, A. D. Da Costa, B. L. Canto Martins +8
Observations of circumstellar disks provide a powerful tool for our understanding of planetary systems dynamics. Analogs to the Solar System asteroid belts, debris disks result fro…
New Suns in the Cosmos II: Differential rotation in Kepler Sun-like stars
M. L. Das Chagas, J. P. Bravo, A. D. Costa +9
The present study reports the discovery of Sun-like stars, namely main-sequence stars with , and rotation periods similar to solar values, presentin…
Kepler rapidly rotating giant stars
A. D. Costa, B. L. Canto Martins, J. P. Bravo +9
Rapidly rotating giant stars are relatively rare and may represent important stages of stellar evolution, resulting from stellar coalescence of close binary systems or accretion of…
Testing the recovery of stellar rotation signals from Kepler light curves using a blind hare-and-hounds exercise
S. Aigrain, J. Llama, T. Ceillier +10
We present the results of a blind exercise to test the recoverability of stellar rotation and differential rotation in Kepler light curves. The simulated light curves lasted 1000 d…
Measuring stellar differential rotation with high-precision space-borne photometry
A. F. Lanza, M. L. Das Chagas, J. R. De Medeiros
We introduce a method of measuring a lower limit to the amplitude of surface differential rotation from high-precision, evenly sampled photometric time series. It is applied to mai…
